You can find much discussion here about sport climbing.
In short, high ropes course (horizontal movement) are not sport climbing (vertical movement) and should not be tagged with sport=climbing.
For the naming I prefer the later suggested climbing_adventure over high_ropes_course.

Taken the definition of sport from wikipedia high ropes course is a sport:
Sport are all forms of usually competitive physical activity which, through casual or organised participation, aim to use, maintain or improve physical ability and skills while providing entertainment to participants, and in some cases, spectators.

Propose high_ropes_course:type=*

Having a "type=*" tag for the type of course is too vague. It should really be "high_ropes_course:type=*". Other than that, the proposal looks good to me --Danstowell (talk) 21:09, 12 January 2014 (UTC)

If we use the key "high_ropes_course" for the type, we can drop the ":type". sport=high_ropes_course + high_ropes_course=indoor. (It is the same scheme like highway=cycleway + cycleway=track) --MasiMaster (talk) 18:01, 17 January 2014 (UTC)

highway=rope_course

I would tag the ways with highway=rope_course to draw a map of them (analogous to highway=via_ferrata which has some 12000 uses now), with additional attributes describing the details of sections (height above ground, which kind of equipment required, typeof (singlerope, 2 or 3 parallel ropes, vertical/horizontal ladders etc), possibly sac_scale. See also Proposed_features/via_ferrata for more inspiration.. I think the two features share a lot.

There is also already approved bridge=yes+bridge:structure=simple-suspension for "Tibetan" bridges, could get some additional attributes. RicoZ (talk) 10:30, 30 August 2014 (UTC)

How about also adding zip_lines to the proposal? They are long enough to be drawn as ways.. highway=zip_line ? RicoZ (talk) 15:54, 5 September 2014 (UTC)
